I'll complete if the ram is supported by model not mb chipset or this is impossible

putting ram not supported on a motherboard will not work at the listed speed of the ram.
you are correct, generally speaking the motherboard is the one that will dictate what max speed ram can run (aside cpu restrictions in some cases).

now if the motherboard permits for example 1866 max speed and you try to put 2400 ram in it, (assuming your matching DDR3 or DDR4 requirements) the ram will more than likely only run at 1866 not at 2400, and you will not be able to overclock it to 2400 either.
in some cases mostly holds true with Hxxx series boards, if the board lists 1600 max ram speed I have seen people putting 1866 ram and it not working on the motherboard, but in most cases the motherboard can run the ram at the speed it can handle it.

what are the make and model of your cpu, motherboard do you have and or ram trying to match to it ?

Ok if I have:
I9-7900x
X299 pro carbon
Vengeance rgb 32gb

MERGED QUESTION
Question from omar80747326 : "What is the effect of unsupported ram"

What will happen if I have ram supported by mode

If the memory is the right type DDR2, DDR3, DDR4) for the motherboard then it will probably work. The new AMD boards are more picky than the Intel boards.

Their some exceptions for the DDR3 the older boards and processors usually don't support todays higher density memory.

most mb vendor cant test all vendor rams that are out there as vendor keep changing part number of the kits. as they get ram chips in lots from different vendors. over the years we lost a few vendors to fab fires and going under. most ram if it uses samsung chips you should not have any issues.

you did not provide the model number of the ram, hard to tell if your using best ram possible for your motherboard.

do you use this one ?

this one would be officially supported by MSI, if it´s the MSI GAMING PRO CARBON AC.

or post the correct modelnumber of the RAM

the effect of non supported RAM is:

it works fine
or
it won´t boot
or
the system is unstable, freezes, shuts down (won´t damage the system though)

if DDR3 would be hammered into DDR4, the motherboard would be dead 😉

Ok I have done a virtual build using pc part picker enabling compatibility filter
X299 pro carbon
i9 7900x
Vengeance rgb model CMR32GX4M2C3200C16W

 

[helpstar]

official compatibility list:
https://www.msi.com/Motherboard/support/X299-GAMING-PRO-CARBON-AC#support-mem-3

model CMR32GX4M2C3200C16W is not officially supported but could run without problems anyways. You will have to find someone who tested it or test it yourself.
